Food Many tribes eat the ripe berries in a variety of forms: fresh off the plant, dried into cakes or bread, soaked in water for a beverage, sun-dried and stored for later use, pies, or jams. They often accompanied fish, dried meat, or for dessert. For some tribes such as the Okanagon, the fruit was a staple in their diet. Young shoots were sometimes peeled and eaten raw or cooked in the spring (Comox)
Dye Thompson Juice used as a stain. Coast Salish combined it with fruits of salal, black twinberry, and wild raspberry for a purple stain.
